Troubleshoot CentOS7.0 networking and centos7.0 networking

1. ifconfig command.

Check whether the network configuration is correct.

Configure the network in/etc/sysconfig/network-scripts/ifcfg-ens32, remember the onboot = on option must be set, otherwise the network cannot start

Onboot = on

IPADDR = 192.168.1.31
NETMASK = 255.255.255.0
GATEWAY = 192.168.1.1

Remember to restart after Configuration

[Root @ localhost ~] #/Etc/init. d/network stop
[Root @ localhost ~] #/Etc/init. d/network start

2. ping the host 127.0.0.1 (if the host can be pinged, the TCP/IP protocol is correct) (PS: Ctrl + C)

3. Check whether the gateway can be pinged. Ping 114.114.114.114

Modify dns
[Root @ localhost ~] # Vi/etc/resolv. conf
Add two dns servers:
Nameserver 114.114.114.114
Nameserver 8.8.8.8
